DETAILED DESCRIPTION OF THE INVENTION

The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

FIG. 1A is a schematic diagram of an exemplary embodiment of a transmission module of the invention. The transmission module 100 comprises an emitter device 110, and reflection devices 130 and 150. The emitter device 110 emits a light L₁₁₀. The reflection devices 130 and 150 are disposed opposing the emitter device 110 to reflect the light L₁₁₀. In this embodiment, the reflection device 130 reflects the light L₁₁₀ to generate a reflected light L₁₃₀. The reflection device 150 reflects the light to L₁₅₀ generate a reflected light L₁₅₀. The energy of the reflected light L₁₅₀ is different from the energy of the reflected light L₁₃₀.

The energy of the reflected light L₁₅₀ is different from the energy of the reflected light L₁₃₀ by controlling the materials, the reflectivity or the reflection areas of the reflection devices 130 and 150. Additionally, the reflection device 130 comprises a radian θ1 and the reflection device 150 comprises a radian θ2. The energy of the reflected light L₁₅₀ is different from the energy of the reflected light L₁₃₀ by controlling the radians θ1 and θ2.

The invention does not limit the kind of the reflection devices 130 and 150 utilized. In some embodiments, one of the reflection devices 130 and 150 is a mirror or a light guiding plate. The invention does not limit the kind of the emitter device 110 utilized. In this embodiment, the light L₁₁₀ emitted by the emitter device 110 is an infrared ray or a laser beam.

FIG. 1B is a top-view of exemplary embodiments of the reflection devices 130 and 150. The reflection devices 130 and 150 approximately constitute a circular shape. In this embodiment, an isolation device 170 is disposed between the reflection devices 130 and 150 such that the reflection device 130 is disposed on an independent plane and the reflection device 150 is disposed on another independent plane.

In one embodiment, the isolation device 170 is a gap to separate the reflection devices 130 and 150. The isolation device 170 is not necessary and may be optionally removed in other embodiments.

Further, the invention does not limit the number of reflection devices utilized. In this embodiment, the transmission device 100 comprises two reflection devices. In other embodiments, the transmission device 100 comprises at least three reflection devices, as shown in FIG. 3B. FIG. 3B shows various reflection devices MR1˜MR8. When the number of the reflection devices is increased, the number of the reflected lights comprising different energies is also increased.

Each reflected light is capable of having particular energy by controlling the materials, the reflectivity, the reflection areas, or the radians of the reflection devices. When an external receiver receives the reflected lights emitted by the transmission module 100, the external receiver obtains the position of the transmission module 100 according to the energy of the reflected lights.

FIG. 1C is a schematic diagram of an exemplary embodiment of the reflected lights L₁₃₀ and L₁₅₀. Each of the reflected lights L₁₃₀ and L₁₅₀ is a radioactive ray. The radioactive scopes of the reflected lights L₁₃₀ and L₁₅₀ constitute a circular light. The oblique lines of FIG. 1C shows the circular light. Thus, an external receiver easily receives the reflected lights L₁₃₀ and L₁₅₀ emitted by the transmission module 100.

FIG. 2 is a schematic diagram of another exemplary embodiment of a transmission module of the invention. The transmission module 200 comprises control devices 210, 230 and reflection devices 250, 270. The functions of the control devices 210 and 230 are the same. The invention does not limit the function of the control devices 210 and 230. In one embodiment, the control devices 210 and 230 have functions of emitting light. For example, when the control device 210 emits a first light, the control device 210 emits a second light. In another embodiment, the control devices 210 and 230 have functions of receiving light. For example, when the control device 210 receives a first reflected light, the control device 210 receives a second reflected light. The operating configurations of the control devices 210 and 230 and the reflection device 250 and 270 are described in greater detail in the following paragraphs.

In this embodiment, the reflection device 250 is disposed opposing the control device 210. Referring to FIG. 3A, the scope P₃₅₀ of mapping of the reflection device 250 covers the control device 210. As shown in FIG. 2, the reflection device 250 is capable of reflecting the light L₂₁₀ emitted from the control device 210 or transmitting the reflected light L₂₅₀ to the control device 210. In this embodiment, the scope P₃₅₀ of mapping of the reflection device 250 only covers the control device 210. Thus, the reflection device 250 does not reflect the light L₂₃₀ or transmit the reflected light L₂₅₀ to the control device 230.

The reflection device 270 is disposed opposing the control device 230. As shown in FIG. 3A, the scope P₃₇₀ of mapping of the reflection device 270 covers the control device 230. Referring to FIG. 2, the reflection device 270 is capable of reflecting the light L₂₃₀ emitted from the control device 230 or transmitting the reflected light L₂₇₀ to the control device 230. In this embodiment, the reflection device 270 does not reflect the light L₂₁₀ or transmit the reflected light L₂₇₀ to the control device 210. The reflection device 250 or 270 is a mirror or a light guiding plate.

FIG. 3A is a schematic diagram of another exemplary embodiment of a transmission module of the invention. In this embodiment, the control device 210 is an emitter 310 and the control device 230 is an emitter 330. The emitter 310 emits the light L₃₁₀ and the emitter 330 emits the light L₃₃₀. The code of the light L₃₁₀ is different from the code of the light L₃₃₀. The reflection device 350 reflects the light L₃₁₀ and the reflection device 370 reflects the light L₃₃₀. Additionally, the control device 210 is disposed within the scope P₃₅₀ of mapping of the reflection device 350 and the control device 230 is disposed within the scope P₃₇₀ of mapping of the reflection device 370.

The emitter 310 emits the light L₃₁₀ according to a first emitting frequency and the emitter 330 emits the light L₃₃₀ according to a second emitting frequency. Thus, the code of the light L₃₁₀ can be different from the code of the light L₃₃₀ by controlling the first and the second emitting frequency. For example, when the emitter 310 emits the light L₃₁₀ according to a first emitting frequency, the light L₃₁₀ may comprise the code 0. When the emitter 330 emits the light L₃₃₀ according to a second emitting frequency, the light L₃₃₀ may comprise the code 1.

Because the code of the light L₃₁₀ is different from the code of the light L₃₃₀, the code of the reflected light L₃₅₀ is different from the code of the reflected light L₃₇₀. Thus, an external receiver is capable of obtaining the position of the transmission module 300 according to the codes of the reflected lights L₃₅₀ and L₃₇₀ when the external receiver receives the reflected lights L₃₅₀ and L₃₇₀.

Additionally, when the external receiver approaches the transmission module 300, the external receiver can receive strong reflected lights. When the external receiver leaves the transmission module 300, the reflected lights received by the external receiver are weak. Thus, the external receiver obtains the distance between the transmission module 300 and the external receiver according to intensity of the received reflected lights.

As shown in FIG. 3A, an isolation device 390 is disposed between the reflection devices 350 and 370. The isolation device 390 prevents the light L₃₃₀ from affecting the reflected light L₃₅₀ and prevents the light L₃₁₀ from affecting the reflected light L₃₇₀. The reflection devices 350 and 370 are independently disposed on the different planes due to isolation device 390. In other words, the reflection device 350 does not contact with the reflection device 370. In other embodiments, the reflection device 350 may contact with the reflection device 370. In such a case, the isolation device 390 (such as a partition) is utilized to obtain different reflection regions.

In this embodiment, the transmission module 300 comprises two control devices and two reflection devices, but the disclosure is not limited thereto. In some embodiments, the number of control devices and the reflection devices are more than two, wherein the number of the control devices is equal to the number of the reflection devices.

FIG. 3B is a top-view of exemplary embodiments of various reflection devices of the invention. The reflection devices MR1˜MR8 are arranged in a circular shape. The reflection devices MR1˜MR8 are independently disposed on different planes. Thus, the reflection devices MR1˜MR8 are not in contact with each other.

For example, the reflection device MR1 does not contact with the reflection devices MR2˜MR8. Similarly, the reflection device MR8 does not contact with the reflection devices MR1˜MR7. In other embodiments, the reflection devices MR1˜MR8 contact with each other, but a partition is disposed between neighboring reflection devices to obtain different reflection regions.

Each reflection region corresponds to one control device. Thus, the control devices can be arranged as shown in FIG. 3C when the reflection devices are arranged as shown in FIG. 3B. Referring to FIG. 3C, the control devices EM1˜EM8 are arranged according to a circular shape. Each control device is disposed within the scope of mapping of the corresponding reflection device.

In this embodiment, the codes of the lights emitted by the control devices EM1˜EM8 are different. Further, the lights emitted by the control devices EM1˜EM8 are radioactive rays and the radioactive scopes of the lights form a circular light similar to FIG. 1C.

FIG. 4 is a schematic diagram of another exemplary embodiment of a transmission module. In this embodiment, the control device 210 is the receiver 410 and the control device 230 is the receiver 430. The reflection device 450 reflects an external light L₁ and generates a reflected light L₄₅₀ to the receiver 410. The reflection device 470 reflects an external light L₂ and generates a reflected light L₄₇₀ to the receiver 430.

In one embodiment, the lights L₁ and L₂ are emitted by an external emitter. Since the external emitter may be disposed in different positions, one reflection device (450 or 470) may receive an external light (L₁ or L₂). When the corresponding receiver (410 or 430) receives the corresponding reflected light (L₄₅₀ or L₄₇₀), the location of the external emitter can be obtained.

In another embodiment, the reflection device 450 receives the external light L₁, and simultaneously, the reflection device 470 receives the external light L₂. In this case, the energy or the codes of the external lights L₁ and L₂ may be different. In one embodiment, the external lights L₁ and L₂ may be the reflected light L₃₅₀ and L₃₇₀. Thus, the receivers 410 and 430 obtain the position of an external emitter according to the energy or the codes of the received reflected lights L₄₅₀ and L₄₇₀ when the reflection devices 450 and 470 reflect the external lights L₁ and L₂ emitted by the external emitter. Furthermore, the distance between the external emitter and the transmission module 400 can be obtained according to the energy or the codes of the received reflected lights L₄₅₀ and L₄₇₀.

To sufficiently reflect the external lights L₁ and L₂ to the receivers 410 and 430, the material, the reflectivity, the reflection area, or the radian of the reflection device 450 is the same as that of the reflection device 470. Additionally, an isolation device 490 is disposed between the reflection devices 450 and 470 to prevent the reflection device 450 from receiving the external light L₂ and to prevent the reflection device 470 from receiving the external light L₁.

FIG. 5 is a schematic diagram of another exemplary embodiment of an electronic system of the invention. The electronic system 500 comprises an emitting module 510 and a receiving module 530. The emitting module 510 and the receiving module 530 utilize a wireless method to communicate with each other. In this embodiment, the emitting module 510 emits lights L₅₁₁˜L₅₁₄. The receiving module 530 receives the lights L₅₁₁˜L₅₁₄ and obtains the position of the emitting module 510 according to the receiving result.

In this embodiment, the lights L₅₁₁˜L₅₁₄ are radioactive rays and the radioactive scopes of the lights L₅₁₁˜L₅₁₄ constitute a circular light. In one embodiment, the position of the emitting module 510 is fixed. The position of the receiving module 530 is actively changed or inactively changed by a user.

The receiving module 530 obtains the position of the emitting module 510 according to the received lights. For example, when the receiving module 530 receives the light L₅₁₁, the receiving module 530 determines that the emitting module 510 is located at the right side of the receiving module 530. Additionally, the receiving module 530 obtains the distance between the emitting module 510 and the receiving module 530 according to intensity of the received lights.

In one embodiment, the emitting module 510 may be the transmission module 100 or 300 shown in FIG. 1A or 3A. In this case, the receiving module 530 is the transmission module 400 shown in FIG. 4, but the disclosure is not limited thereto. In some embodiments, other receivers can serve as the receiving module 530 when the emitting module 510 is the transmission module 100 or 300.

In another embodiment, the receiving module 530 is the transmission module 400 shown in FIG. 4. In this case, the emitting module 510 can be the general light emitter. Since the transmission module 400 comprises the receivers 410, 430 and the reflection devices 450 and 470, the position of the emitting module 510 can be obtained according to the received result of the receivers 410 and 430.

When the transmission module comprises various reflection devices and a single emitter device as shown in FIG. 1A or comprises various reflection devices and various emitter devices as shown in FIG. 3A, various lights having different energy or having different codes are reflected. One external receiver obtains the position of the transmission module according to the reflected lights generated by the reflection devices.

Additionally, when the transmission module comprises various reflection devices and various receivers as shown in FIG. 4, the position of an external emitter or the distance of the external emitter and the transmission module can be determined according to the received result of each receiver.
